実験手順: The mixture of [4-(tert-butyldimethylsilanyloxy)butyl](3-nitro-quinolin-4-yl)amine and tert-butyldimethylsilanol (110 g) from the previous step was dissolved in toluene (880 mL) and placed in a Parr hydrogenation vessel along with 5% platinum on carbon catalyst (3.0 g). The vessel was pressurized to 50 psi (3.4×105 Pa) hydrogen and shaken on the Parr apparatus for 1.5 hours, occasionally adding additional hydrogen to maintain a pressure of 50 psi (3.4×105 Pa). After 3 hours, the reaction mixture was filtered through CELITE filter agent and concentrated under reduced pressure to provide N4-[4-(tert-butyldimethylsilanyloxy)butyl]quinoline-3,4-diamine as a dark oil that was used directly in the next step without further purification. to maintain a pressure of 50 psi (3.4×105 Pa) After 3 hours the reaction mixture was filtered through CELITE filter agent concentrated under reduced pressure

実験手順: Trifluoroacetic acid (154 μl) was added to a solution of (4R)-4-t-butyldimethylsilyloxy-2-cyclopenten-1-one (5.79 g, 27.3 mmol) and benzylbutoxymethyltrimethylsilylmethylamine (15.4 g, 55.0 mmol) in dichloromethane (100 ml) at room temperature, followed by stirring for 20 minutes. A saturated sodium hydrogencarbonate aqueous solution was added to the reaction mixture, and the mixture was extracted with ethyl acetate. The organic layer was washed with a saturated sodium chloride aqueous solution and dried over anhydrous sodium sulfate. After removing the solvent by evaporation, the residue was purified by silica gel column chromatography (n-hexane:ethyl acetate=1:1) to give 4.21 g (19.7 mmol, 72%) of the title compound as a colorless oily substance.
